Flashcards do conjunto (16)
- 1What are the subatomic particles in a nuclei?Proton, Neutron, and electron.
- 2What are shells?Levels that electrons sit at a distance away from centre.
- 3Why do atoms contain equal amount of protons and electrons?Atoms like to have a neutral charge.
- 4What is the charge of a proton?+1
- 5What is the charge of an electron?-1
- 6What is the charge of a neutron?0
- 7How much bigger is the atom compared to its nucleus?100000 times bigger. Most of the atom is empty space.
- 8What are the atomic masses of a: proton, neutron, and electron?1,1,0.
- 9What does the atomic nuclei contain?Protons and neutrons.
- 10What is between the nuclei and electron shells?Empty space.
- 11What was Rutherford's experiment?He shot alpha particles at gold foil?
- 12What where the results of Rutherford's experiment?Some of the particles bounced back. Most went straight through.
- 13Why did Rutherford's experiment have such results.Most of an atom is empty space between shell and nuclei. The alpha particles went straight through. Others bounced of the nuclei.
- 14What is an atomic number?The number of protons in an atom. (often called proton no.)
- 15What is atomic mass?The mass of the nucleus (masses of protons + neutrons)
